[0027] Reference Figures 1-5 A module structure for an integrated control system, comprising: The module housing 1 has an opening at the top and a battery cell assembly 2 is installed inside.

[0028] Furthermore, the module housing 1 is made of flame-retardant PPS material, and the positive / negative lead-outs 4 are made of copper material.

[0029] The bottom of the module cover 3 has a boss that extends downwards to correspond to the opening, which is used to seal the module housing 1.

[0030] Furthermore, such as Figure 1 As shown, this improves the sealing performance of the module cover 3 for the battery cell assembly 2.

[0031] The insulating pillars have a rectangular cross-section and are set to eight, which are respectively installed at the four corners and the four centers of the module cover 3.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the insulating pillars provide support at four corners and four center points for the control board 8, ensuring a tight connection between the control board 8 and the surrounding structure. The rectangular cross-section design of the insulating pillars results in a larger moment of inertia on the longer side, enhancing resistance to bending deformation and increasing the creepage distance, thus reducing the risk of air gap breakdown.

[0033] The module cover 3 also includes: A rectangular connecting groove 31 is provided on the top of the module cover 3 for connecting the corresponding insulating post; The first electrode fixing hole 32 is opened on the top of the module cover 3, and the power supply core electrode passes through it; The slot 33 is opened in the first tab fixing hole 32 and is used to lock the tab bus 41 to enhance the stability of the connection between the module cover 3 and the tab bus 41. A perforated groove 34 is formed inside the first electrode fixing hole 32, through which the power supply core electrode passes and is connected to the electrode bus 41.

[0034] Furthermore, the module cover 3 is made of flame-retardant PPS material.

[0035] Both slots 33 located at the positive and negative terminals of the battery cell tabs have outward-opening notches.

[0036] Furthermore, such as Figure 1 As shown, this makes it easy to identify the positive and negative terminals of the battery cell tabs.

[0037] The electrode busbar 41 also includes: The electrode busbar 42 is fixed inside the electrode busbar 41; The second tab fixing hole 43 is opened on and passes through the tab bus unit 42 to fix the battery cell tab and ensure reliable electrical connection.

[0038] Voltage and temperature acquisition board 5 also includes: The hexagonal support 7 is located between the voltage and temperature acquisition board 5 and the control board 8, and is used to connect the voltage and temperature acquisition board 5 and the control board 8. A limiting hole 51 is provided on the outside of the voltage and temperature acquisition board 5 for mounting the hexagonal support 7 and the control board 8. Temperature acquisition interface 52 is installed on one side of the top of voltage and temperature acquisition board 5 and is used to connect a temperature sensor to acquire cell temperature data. The acquisition fixing hole 53 is opened on both sides of the voltage and temperature acquisition plate 5 and corresponds to the opposite pole. It is used to fix the voltage acquisition line and connect the battery cell tab to acquire voltage data. Pan head screw 6 is located on the top of voltage and temperature acquisition board 5 and is used to connect voltage and temperature acquisition board 5 and electrode bus 41.

[0039] The battery cell assembly 2 is fixed inside the module housing 1 and the module cover 3. The battery cell tabs extend upward and pass through the second tab fixing hole 43 and the acquisition fixing hole 53 respectively to connect with the voltage and temperature acquisition board 5. During this process, they are folded in pairs and attached to the surface of the tab bus 41.

[0040] Furthermore, the voltage and temperature acquisition board 5 is able to detect cell voltage and temperature data.

[0041] Control board 8 also includes: The data communication interface 81 is located on the top of the control board 8 and is used to communicate with the host computer to transmit data such as voltage and temperature. The control chip 82, located on the top of the control board 8, is used to analyze the collected data and execute safety control strategies. The power interface 83 is located on the top of the control board 8 and is used to connect an external power source to power the control board 8. Countersunk screw 9 is located on the top of control plate 8 and is used to fix control plate 8 to the top of hexagonal support 7.

[0042] The voltage and temperature acquisition board 5 and the control board 8 are separated by the hexagonal support 7.

[0043] Furthermore, such as Figure 1 As shown, this allows air to circulate between the voltage and temperature acquisition board 5 and the control board 8, facilitating heat dissipation for both boards.

[0044] Working process and principle: After the battery cell tabs pass through the perforated slots 34 of the module cover 3, they are fixed to the copper tab busbar 41 by pan head screws 6, which collects electrical energy and outputs it to the outside through the positive / negative lead-out busbar 4; the voltage and temperature acquisition board 5 is installed close to the tab busbar 41 to collect the battery cell voltage and temperature data in real time. After being processed by the control board 8 connected by the hexagonal support 7, the data is uploaded to the host computer through the data communication interface 81 to realize status monitoring and abnormal protection.
